Application flied September 23, 1812, Serial No. 721.785. Renewed Septemberl'i, 1918. Serial No. 790,858.

To all Whom it may (mu-era lie it known that I, \VILLmn J. XEIDIe, :1 citizen of the l nited Staten-residing at Madison. in the county of Dane. State of Wisconsin, have invented a certain new and .useful Improvement in lypedl'riting Ma chines. of which the following is a specifi cation, reference being bad therein to the :ueompanying drawings.

(er ain principles and features of my mvention as described herein are included within the generic invention which is described and claimed in my (o-pending: application filed April 20. 1908, Serial No. 425.212. ()ue branch of my said generic invention supplies the operator of a type- 'Wl'ltillfl machine with indicating means,

controlled by the sheet upon which he is writing, for indicating successive positions of the leading end of the sheet and for warning him of the arrival of one or more points on the sheet a predetermined distanee therefrom into printing position. The present invention supplies the operator with such means.

The present invention is distinguished by the employment of an operative member which is supplied with driving devices for giving it movement coiirdinate with that of the platen at a. predetermined point in the progress of the leading end of the sheet, and which is releasable from the control of said devices. and which is supplied with means operatingrto return it into initial position when released from such control, and through which the said indicating means. comprising in this case indices and various types of visual. audible and machine-lock signaling devices, are called into operation at predetermined sheet-positions.

Certain features and combinations as shown. described and claimed herein are also intended for indicating uses in connection with other branches of my broader invention aforesaid.

In the draWings,-l igure 1 is a view in side elevation showing a portion of a typewriting machine with my invention applied thereto. Fig. 2 is a view in front elevation of a portion of the same, with the carriage indicated in section. Fig. 3 is a detail view. partly broken away and partly in section, of operative ember (hand some of its con- 11801310118. Fi 4 is a view in section of certain parts on the linhl, Fig. 1. Fig. 5 is an end elevation of a portion of a typewriter carriage showing a modification in the form and mounting of the sheet-controlled elements of Figs. 1 and 2. Fig. 6 is an end elevation another modification. Fig; 7 is a front view of the parts shown in Fig. ti, with the platen arbor added. Fig. 8 is an end elevation partly broken "away and partly in section of a modification in which the control is by the bottom end of the sheet instead of the leading end.

With reference to the drawings-The usual stationary main frame of a typewritine' machine is indicated at 18, and the end of the usual transversely movable carriageframe at 1.2. in which is journaled platen arbor 13 hearing platen 10 attached thereon. the said platen and its arbor being 1'0- tuted in usual manner by line-space mechanism not shown herein. As referred to th e parts are old in the art and may be of any approved type. ()ther usual typewriter parts not shown herein are or may be as in practice.

The embodiment of m invention that I prefer to employ is app ied to the abovenamed typewriter structure as follows: A toothed wheel 11 is conveniently attached at the end of the platen by screws 17 so as to rotate in unison with the platen and serve as a driver. Adjacent to said wheel but operative independently thereof is operative member 6 having a toothed rim 5 attached thereto. Shouldered pin 20 on carriage frame 12 has jonrnaled thereon sleeve :21, fixedly attached upon which is arn1-22 bearin pin 3 upon which are journaled the toothe rider-wheels 5 and 11. connected to rotate in unison, wheel l3 being adapted to mesh with toothed rim 5 and wheel 11 with toothed driver 11 so as to connect rim 5 to be driven by wheel 11. The relative diameter of the several wheels may be as desiredI prefer to gear down rim 5 so that it will revolve more slowly than the driver 11. Also fixedly at,- tached upon sleeve 21 is paper-feeler 28 supplied with a paper-contacting roller-end 28' ournaled on pin 24 on the feeler. Plnten 10 IS supplied with a ci cumferential openin or slot 4, into which the roller portion 28 of paper-feeder 284ml; its path in the absence of the paper-sheet, the weight of arm 22 and wheels 5Kand 11' tending to press the said roller portion of the paper-feeler into the slot, which is made shallow so to limit the entering movement thereof. Operative member 6 previously referred to is preferably given the form of a revoluhle drum, supported from a ventral llllll or hashing 26 (see Fig. 4) which is jonrnaled on platen arhor 10. The outer or l'are wall of said drum (Fig. 3) has a ventral aperture therein, into which projects one end of a split post 727 attached to earriage frame in. Inside said drum :1 resilient frietion-riin, T presses radiallv outward into frictional engagement with the rim of the drum. One end of a coiled spring is attached to said ring, the other end being secured in the cleft-of post 27. The purpose of the friction-ring is to prevent over-winding the spring. Drum P bears a fixed projection 3 3, in the path of which stop 31, pivot d on pin 30 on earriage frame 1:2, is maintained by an at 54 adapted to enter'hetween the teeth of toothed wheel 11 and look said wheel against forward rotation, but normally maintained out; of loekin iosition by its own weight and that of weig t 56. It will he understood that arms -41" and 51* operate in dill'erent planes, and that projections 40 and 3t) move in radially di lierent paths, so that projertion it) roiiperates only with arm 41 and pro jretion 5U onl with part 51".

Drum l is supplied with indires preterahly arranged in asrending order, and is thus an index-Carrier. cooperating stationary index 34 is attached to earriageframe 12 in eonrenient position it is illlmaterial whether the indires he of the kind shown, or in any especial order, or that the indication begin with any esperial position ol the sheet. A rolonsegment (3 of paper or the like may he attarhed as by means of paste in any' desired angular position upon lug 33, alsoattae ed to stop 31, against po Sitioirstop 35 on the rarriageirame. V Spring 23% tends to rotate the drum so as to bring the drum into initial position with projection 36 hearing against stop 31. arriage frame 12 also hears; on an upstanding porlion thereof an inwardly projerting pin ill,

is limited by lugs 41" and 41. which are bent over to engage with arm 41 as against a stop. Arm 41 projerts into the path of projection 40, which is adapted to h serewed into any one of the threaded holes l0 in the fare.

wall of drum 6, thus heing angularlv adjustable upon said drum. Carriage-twine 12 also hears inwardly planer-ting pin 52. on whieh is j urnaled ha i 57. Radiating from the drum; to eoiiperate with index 34.

The merhanism operates as follows: in

the absence of the sheet the roller portion of.

paper-feelei 28 has a position in slot 4. Wheels 5" and 11" are out of engagement with wheels 5 and i1, and drum ll, free of engagement with the platen. stands at rest with PIOjf'tllCll 36 held against stop 2'51 hy spring 25. The paper-sheet is entered in usual manner down papentahle S on rarriage frame. 12. and advaneed as usual by the platen. which as regarded herein is the prineipal feed-roll for feeding the sheet through the marhine. Eventually the leading end of the sheet eneounters the roller portion of paper--i'eeler 28 and i ais it out of slot 4. thereby roeking sleeve Eli. and throwing wheels 5" and 11 into engagement with wheels 5 and 11. therehv eonnerting drum 6 with the platen. The drum thereafter moves coordinately with the sheet, and may he supplied with indiees that will indicate the progress of the sheet. When the first line position on the sheet comes into printing position, for instanre, the point on the drum or indexwarrier then in indieating position adjarent to the fixed index 34- may be supsaid huh in upward direetion is arm 51 hear- 3 mg in .'.l" on whieh is, ournaled arm 5i 1 having :1 lug id to engage upon said arm ill and limit the movement of nrin 51 thereon. A working portion 51 of said arm Til pro jet-ts into the path o'l projeetion 5t), whieh is adapted to he serewed into any one of the threaded hole; in the fare wall l' drum (3, thus hem angularly adjustable on said drum. position-stop 55 on earriageframe l2 limits the movement. of arm 5] in one di reetion; while weight 56 fixedly attached on plied with an index i. and for the next lineposition with in index 2. and so on, at will. Continued advance of the she t will hring (o OP-Shgmefll; G into view from heh ind shieldpointer 34 at the predetermined time, thus giving; the operator :1 visual signal that. his sheet has arrived into prmletermined position. l"'oieetion 40 will also he iii-ought against or; '11 at a predetermined time, and press it downwardly, raisin; hell-hammar 45. which with continued movement of Sand projeetion will he released when the projertion rlears said arm and strike the hell. giving the. operator an audible signal as to his shoetposition. And projertinn .70 will he brought into engagement with part 5]" likewise, rot-king lever 51 at the predeterno i mined time and through hub 57 causing arm 53 to lift tooth 54 into locking engagement with wheel 11, thus renderin a portion of the pewriter mechanism, namely in this case I: e sheet-advancing means, inoperative for use. The operator is enabled at will to release the locked mechanism by pressing arm 51 toward the platen arbor until projection 50 clears part 51". 10 The knuckle-joint relationship between arms 41 and 41 hereinbefore described is a vision to permit projection to move Ev'vlrdly past arm 41", lug 41 separating E arm 41 in such an action, and lug t! '15 preventing displacement of the parts. Pro- Jection may be backed past part 51" in a similar manner, lug 51 separating from arm 51, and rojection 36 moved forwardly past stop 31, iig 33 separating from positimbst p 35 and permitting the movement.

In Fig. 5 is illustrated a modification in the form and position of the sheetcont ruled arts of the mechanism. Carriage-frame l) ars inwardly projecting pin 20, on which is journaled sleeve 21 having fixed thereon arm 22' and paper-feeler 28. the arm 22 being mounted between the carriage-frame and the paper-feeler, and having a pin 3*- thereon. Journaled upon this pin and re vol vin unison are the rider-wheels 5" and 11 adapted to mesh with wheels 5 and 11 previously described. Instead of the cit-ruin crential slot 4 in the platen, a slot 4 iu'thc aper-table is employed into which papereeler 28 has its path for a limited distance. The remainder of the mechanism is i as has been described. The paper-sheet i1. entered in usual manner down paper'tablc 8. the leading end thereof raising paper-feeler- 28' out of slot 4. thereby rocking sleeve 2] and throwing wheels 5 and 11 into mesh with wheels 5 and 11. The loading cud of the sheet is advanced into the angle between feed-roll 10 and the platen in usual man ner, before the platen is turned. The platen is then revolved, advancing the sheet and also moving drum 6 from its preattained initial position. lVhen the sheet is tltlVtUlCUl into the first line position that portion or drum 6 adjacent to stationary index 3-1 may be supplied with an index 1 if desired, and with an index 2 for the next line position and so on, as before. The papeufeeler in this case does not terminate in an antiiriction roller, the figure being intended in con nection with the earlier figures to illustrate something of the different forms and positions of pa er-i'eelers possible to be used in such a. wee anism.

Still a difierent form of papenfeclcr is illustrated in Figs. 6 and 7, at 28 Carriage-frame 12 bears inwardly projecting pin 20", on which is journalcd sleeve 21" bearing arm 23*, one branch of which is supplied with a pointer 34. Pin 13 carried on said arm has journaled thereon drum 6', supplied with indices in a double row, the second row being a continuation of the first. so as to give a range of indication of two revolutions of the drum. Platen 10 is supplied with the same circumferential slot previously described in connection with the earlier figures, into which paper-feeler 28", which here takes the form of a ridge or slotcutering circlmiferential feeling and driving paper-contzu-ting part upon the periphery of the drum, has its path in the abscnco of the sheet, being maintained out of engagement with the bottom of the slot by posiiioirstop it) on carriage-frame 12 in cooperation with arm 23. A weight 35 is eccenlrically attached upon the drum. During the absence of the sheet. as in the illustrations. the drum (5" is brought into and nmintnined in a constant initial position by the action oi weight 25. The sheet is entcrcdand advanced as usual. When the leading end thereof encounters papcr-fecler 28 it lifts it out of slot 4. Thereby drum 0 is caused to rest upon the sheet. Further advance of the sheet causes a rotation of the drum through the frictional contact of the driver or paper-feeler 28 with the sheet. from said initial position of the drum, and the line-positions relatively to the leading end of the sheet can be indicated as before by indices on the drum, except that in this case the drum is not geared down, and after one revolution thereof the indices are continued in a second column or row for the re mainder of the progress of the sheet. It is to be noted that in both the preferred form of the device and in the several modifica- [ions he device is automatically reset.

Fig. 8 is a representation of a modification in which the indicating mechanism dc- 9 ..1'lbttl in connection with Figs. 1 to 4 is contiollcd by the button. end of the sheet, instead of by the leading end. and in which the various indicating features are automatically opcrated with relation to the position of the bottomend of the sheet. Atin hed lo platen 10 by convenient means. such as screws 17, is toothed wheel 11. to act the driver element of the mechanism. Drum 6 having toothed rim 5 attached, is constructed. as before described. so as to be returned into initial position by spring 25. with projection 33 restiu against stop 3!, and the other parts of tie mechanism are constructed as described in connection with Figs. 1 to 4, except that the upstanding portion of carriage frame 12 bears the inwardly projecting axle 20, which is longer than axle 4-" in Figs. 1 and 2, and which in addition to having journaled thereon sleeve 42 adjacent saidirame, as in Figs. 1 and 2 (but not necessary to be shown in Fig. 8) has also journaled thereon at the end of said sleeve the independent sleeve 21, upon till which is fixedly attached an arm 22 hearing pin 3" at the end thereof, and upon which is also fixedly attached it paper-feeler 28 having movement into it slot or opening in the paper-table 8, indicated at 4. A ridergear 5 is jnm'nnled on Illl 3" in such manner as to engage with hoti toothed wheels 11 and 5 when llllli 2'2 is lowered, but to he clear of engagement with said wheele when pnper-fceler 2S resting olvsheet, l maintains arm 22 in rni eil position, as in the illllfill'tb tion. It will he understood that axle 21) of Figs. 1 and 2 and the parts; mounted thereon are not employed in this modification. n t is the i-ircnmferentinl slot 4 in the platen.
